AMD Southern Islands vs. NVIDIA Fermi/Kepler On Gallium3D

Phoronix: AMD Southern Islands vs. NVIDIA Fermi/Kepler On Gallium3D

Yesterday I posted benchmarks of the AMD RadeonSI Gallium3D driver looking at the open-source driver performance for the Radeon HD 7000 series graphics cards. The performance is comparatively very poor right now compared to earlier generations of AMD Radeon hardware that is better supported. But how does the open-source performance compare between the AMD Radeon HD 7000 series and the NVIDIA GeForce 400/500/6000 "Fermi" and "Kepler" on Nouveau? Here's benchmarks...

Micheal, thanks for doing the benchmark--I remember the requests for this.

But, could someone run this benchmark with an HD5xxx/HD6xxx in a similar system (quad-core i7 4770k with HT @ 3.5 GHz/16 GB RAM, 1920x1080 display, SSD), or an intel gpu?
At least I think that's a quad-core with hyperthreading...Micheal, is that correct, or did you get an octocore?

Very roughly, it looks like the 7850 is competing with the GTX 550, and the the 7950 with the GTX 680.
Reaction Quake runs better on nouveau.

Nah, it's just Gallium3D for SI not being in the greatest shape (compared to r600)

Michael didn't mention what power management option he was using either. I assume he was using the old style power management, but he didn't say if he forced the high GPU profile or not. He also didn't specify which shader compiler was used. I believe the LLVM compiler is the default now, but occassionally the old compiler is faster (both are slower than R600sb of course, although that is unsupported with SI)

The 4770K is a quad core with HT, yes. The only octacore Intel CPUs are Xeons, and they cost at least 3000€.
